Keeping tabs on the air in your tires is hard enough! You shouldn’t have to worry about a flashing tire pressure light after you’ve gone to the trouble of inflating them. Although your tire pressure monitoring system is a crucial component in your vehicle, seeing a TPMS light on when it shouldn’t be isn’t necessarily a reason to fear the worst.

Learning how to reset your tire pressure light only takes a few minutes, and if you need a little help, the experts at your local Sid Dillon service center are always happy to be of assistance!

Resetting Your Tire Pressure Light

In most cases, inflating your tires to the proper level will cause your TPMS light to go off all on its own. If correcting your pressure levels doesn’t cause the light to go off, there are a few simple steps you can take to narrow down the range of possible issues:

  • Some vehicles need to move a little before their TPMS lights will reset. Drive above 50 mph for ten minutes. When you next start the car, the light should turn off.
  • Drivers can also perform a hard reset by turning the vehicle off, then turning the key to the first “On” position in the ignition. Hold down the TPMS reset button, and wait for the TPMS light to blink three times. Release the button, start the car, and wait 20 minutes for the sensor to refresh. The light should now turn off.
  • You can also start from scratch by filling your tires to 3 psi over the recommended amount, then deflating them completely. (Remember the spare, as it may also have a pressure sensor!) Once all tires have been emptied, reinflate them until they’re at their recommended levels.
  • You can also cut power to the TPMS, so it has to reset itself. Disconnect the positive battery cable with a wrench. Then turn the car on and honk the horn, diffusing any remaining power in the vehicle. Reconnecting the battery should allow your TMPS light to get a correct read on your pressure levels, and turn off.

What Does a Flashing Tire Pressure Light Mean?

If your light stays on after you fill your tires, the system is probably having trouble detecting the correct levels. However, if you’re facing a flashing tire pressure light, you might be dealing with a broken sensor, or with a dying battery. In these cases, it’s a good idea to schedule service with your local Sid Dillon service center. We’ll figure out the cause of the problem and get you back on the road in no time.
